There are two suites of tests for this repository. The first is spec/htmlbook_spec.js and tests the package for expected output. Run this test with the following:

$ jasmine-node spec/htmlbook_spec.js

The second test suite checks to be sure that the file being tested in htmlbook_spec are in fact being output to valid HTMLBook. It's no use writing tests that pass unless they pass on valid output. These tests are separated because the validation takes longer.
